[Second Embodiment]
Next, a second embodiment of the present invention will be described. In the following description, the same parts as those already described are denoted by the same reference numerals and the description thereof is omitted.
In the first embodiment described above, on the condition that the communication terminal device 19 periodically receives the registration number of the selected work mode and the registration number is changed, the management server 20 receives the update information including the registration number. I was sending.
On the other hand, the present embodiment is different in that update information is transmitted to the management server 20 when any one of the on / off state of the attachment control mode, the attachment identification information, and the attachment setting number is changed. .
Specifically, the processing unit 18C of the multi-monitor 18 assigns a sequence key corresponding to the setting information, and the storage unit 18D stores the sequence key. When the setting information is updated, the sequence key is newly updated.
The communication terminal device 19 periodically receives a sequence key from the multi-monitor 18. When the sequence key is updated, the communication terminal device 19 updates the setting information stored in the storage unit 19B to the setting information newly stored in the multi-monitor 18. Further, the communication terminal device 19 transmits the setting information to the management server 20 when the sequence key is updated.

The implementation method of this embodiment is demonstrated based on the flowchart shown in FIG.
The processing unit 18C of the multi-monitor 18 periodically outputs the currently set sequence key to the communication terminal device 19 (step S11).
Here, the sequence key is changed when a set value such as an attachment name, a set flow rate, or a set pressure is changed. Specifically, as shown in FIG. 4, when the image G1 is displayed on the screen 18A of the multi-monitor 18, the area G13 to the area G15 can be changed without changing the work mode registration number of the area G12. Changing any of the set values changes the sequence key.
When the operator operates the button 18B of the multi-monitor 18 to change the setting values in the region G13 to the region G15, the processing unit 18C accepts the change of the setting value (step S12).
The processing unit 18C performs setting change confirmation processing according to the change of the setting value (step S13) and updates the sequence key (step S14).

The processing unit 19A of the communication terminal device 19 periodically receives the sequence key output from the multi-monitor 18 (step S15).
The processing unit 19A determines whether the periodically received sequence key is the same as or different from the previous sequence key (step S16).
If it is not different from the previous sequence key (S16: No), the process returns to step S15.
If the sequence key is different from the previous sequence key (S16: Yes), the processing unit 19A requests a setting value from the multi-monitor 18 in order to synchronize the setting (step S17). The multi-monitor 18 outputs a set value in response to a request from the communication terminal device 19 (step S18).

The communication unit 19C transmits setting information including the changed setting value to the management server 20 via the communication line, the base station 21, and the network 22 (step S19).
Setting information output from the communication terminal device 19 is input to the input / output unit 20A of the management server 20 via the communication device 23 (step S20). After predetermined processing is performed by the processing unit 20B, new setting information is stored in the storage unit 20C (step S21).

  According to this embodiment, the communication terminal device 19 and the management server 20 can grasp the setting information for operating the attachment of the excavator 1. As a result, for example, the management server 20 can grasp a setting such that the attachment is operating with a large load. In the present embodiment, information transmission to the management server 20 may be performed in the same manner as other examples.

[Third Embodiment]
Next, a third embodiment of the present invention will be described.

Obtaining and generating attachment operation information.

On the other hand, in the present embodiment, as shown in FIG. 8, a swash plate sensor 11C is provided in the hydraulic pump 11 of the hydraulic circuit of the hydraulic system 10, and the pressure between the attachment valve 13 and the attachment cylinder 8C is reduced. Sensors 13B and 13C are provided.
The processing unit 19A of the communication terminal device 19 then detects the maximum flow rate of hydraulic oil detected by the swash plate sensor 11C between the selection start date and time when the attachment is used and the selection end date and time when the attachment is used, and the pressure sensor 13B. The difference is that the maximum pressure detected at 13C is acquired.

As shown in FIG. 8, the hydraulic system 10 is the same as that of the first embodiment, but a swash plate sensor 11 </ b> C is provided in the vicinity of the hydraulic pump 11. Further, pressure sensors 13B and 13C are provided on the bottom side and head side pipelines between the attachment valve 13 and the attachment cylinder 8C, and the detected values are output to the pump controller 16.
As shown in FIG. 9, the pump controller 16 includes a maximum pressure determination unit 161 and a swash plate angle state determination unit 162.

The maximum pressure determination unit 161 receives the pressure value of the attachment cylinder 8C detected by the pressure sensors 13B and 13C.
The swash plate angle state determination unit 162 receives the value of the swash plate angle of the hydraulic pump 11 detected by the swash plate sensor 11C.
The maximum pressure determination unit 161 outputs the input pressure value between the selection start date and time when the use of the attachment is started and the selection end date and time when the use of the attachment is ended as a maximum pressure to the multi-monitor 18 to determine the swash plate angle state. The unit 162 outputs the input swash plate angle value between the selection start date and time when the attachment is used and the selection end date and time when the attachment is used as the maximum flow rate to the multi-monitor 18. The maximum pressure and the maximum flow rate acquired by the maximum pressure determination unit 161 and the swash plate angle state determination unit 162 are reset when the use of the attachment is finished.

In addition, the determination method of the maximum pressure outputs when the detected value in the pressure sensors 13B and 13C in which the attachment is operating becomes the maximum value as the maximum pressure. Since the maximum pressure is a value detected by the pressure sensors 13B and 13C, the maximum pressure may be lower than the set pressure set by the multi-monitor 18 depending on the operating state.
The maximum flow rate is detected based on the swash plate angle detected by the swash plate sensor 11C by the same method as that for the maximum pressure.

As shown in FIG. 9, the maximum pressure and the maximum flow rate input to the multi-monitor 18 are output to the processing unit 19A of the communication terminal device 19, and input to the maximum flow rate acquisition unit 32A and the maximum pressure acquisition unit 33A of the processing unit 19A. Is done.
When the work mode registration number is not changed, the attachment actual operation information calculation unit 39 determines the maximum flow rate of the hydraulic pump 11 acquired by the maximum flow rate acquisition unit 32A and the electromagnetic variable relief valve 15 acquired by the maximum pressure acquisition unit 33A. Acquire maximum pressure. When the work mode registration number is changed, the attachment actual operation information calculation unit 39 has the electromagnetic variable relief valve 15 acquired by the maximum flow rate and maximum pressure acquisition unit 33A of the hydraulic pump 11 acquired by the maximum flow rate acquisition unit 32A. Determine the maximum pressure. The attachment actual operation information is calculated using the determined maximum pressure and maximum flow rate.

Also according to this embodiment, it is possible to enjoy the same operations and effects as those described above.
In addition, according to the present embodiment, the attachment actual operation information is calculated based on the actual maximum flow rate of the pump 11 and the maximum pressure of the electromagnetic variable relief valve 15, so that the actual operation is closer to the actual operation. The load on the vehicle body can be determined, and more accurate attachment actual operation information can be calculated.
